The Wiggles were founded in 1991 by Anthony Field, Murray Cook, Jeff Fatt, Greg Page and Phillip Wilcher. They were inspired to create an album of children's music based upon concepts of early childhood education. The group augmented their act with costumed characters Dorothy the Dinosaur, Henry the Octopus and Wags the Dog. They have earned multiple Gold, Platinum and double Platinum records; have sold 23 million DVDs and 7 million CDs; and have performed, on average, to one million people per year. The band has earned multiple awards and been inducted into the ARIA Hall of Fame.
